DOOR oR WINDOW PROTECTOR.

SPECIFICATION forming part of Letters Patent No. 537,741, dated April16, 1895.

Application filed July 10, 1 8 94..

To aZZ whom it may concern:

Be it known that I, OLAEs J. ANDERSSON, a subject of the King of Swedenand Norway, and a resident of Lynn, in the county of Essex and State ofMassachusetts, have invented new and useful Improvements in Door orWindow Protectors, of which the following, taken in connection with theaccompanying draw ings, is a specification.

the line 3-3 shown in Fig. 1 Fig. 4 IBPI'B'.

sents a similar cross section showing the device in its locked position;and Fig. 5 represents a vertical section on the line 55 shown in Fig. 4.

Similar letters refer to similar parts whereever they occur on thedifierent parts of the drawings.

In the drawings I have represented the invention as applied to a window,but it is equally well adapted for doors or other wall openings as maybe desired without departing from the essence of my invention.

In the drawings, A, A, represent the uprights of a window frame on whichA represents the upper horizontal portion and A the sill as usual.

B and B represent the windows as usual.

At or near the upper portion of the window frame are secured suitablebrackets O, O, in which is journaled a metal roller D to one end ofwhich is attached a hoisting cord or wire cl which may be suitablyguided over pulleys E, E, as shown in Fig. 1.

In practice I prefer to connect all the rollers D- on the door or windowopenings throughout-the building to one single hoisting cord so that allthe protectors on the doors or Windows in the building may be raised andlowered simultaneously. This however, may depend upon the constructionand arrangement of the building, that is, if so desired, each door orwindow may have an independent raising and lowering device for itsprotector,

Serial No. 517,043- (N'o model.)

or two or more of the said rollers D may be connected together so as tobe simultaneously actuated by a single cord when so required. To theroller D are secured two or more chains f, f, to which are attached at asuitable distauce apart a series of horizontal metal bars F, F, F, theends of which are guided in grooved vertical guide plates G, G, securedto the uprights A, A, or other part of the door or window opening as maybe most convenient and practical. To the inner portion of each groovedguide G is hinged a Vertical locking plate H having a series of notchesor recesses h, h, adapted to receive the bars F, F, when in their lowestpositions and when said locking plates are swung inward as shown inFigs. 4: and 5. Said locking plates are turned into locking positions byan automatic device as soon as the protector bars F F reach their lowestpositions. For this purposeI have shown at the lower end of each groovedguide G a weighted rock lever I pivoted at i and having on its inside acam surface or projection 1 adapted to be actuated by contact with thelowest bar F as it reaches its lowest position causing the upper end ofthe lever I to impinge against the hinged locking plate H whereby it isswung inward until the ends of the bars F, F, are received in thelocking notches or recesses h, h, whereby said bars F, F, are held frombeing raised until the locking plates H, H, are released by the personin charge of the room or building.

Having thus fully described the nature, construction, and operation ofmyinvention, I wish to secure by Letters Patent and claim- In a door orwindow protector, the combi nation with a roller mounted in bearings, aseries of chains connected to said roller and carrying a series of bars,and curved end guides for the bars,of pivoted, notched locking platesfor locking the bars in position, and a weighted rock lever having a camsurface which is engaged by one of said bars, causing said lever toswing the pivoted notched locking plates into position to lock saidbars, substantially as described.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses, on this 30th day of June, A. D.1894.
